Hello!
Not so long ago I thought about how to update my home network and due to the fact that there should be 4 Internet channels at home, one of which GiPon chose Mikrotik, since RB4011 is the only router that supports the necessary SFP modules, but since it does not have USB ports , and they will be needed for the LTE Modem, the question arose about what would have to be bought either MikroTik CRS125-24G or hAP ac.
So the question is, does Router OS have the ability to create a Stack between different devices but with the same operating system in order for them to form one network? And is it possible to create a stack not by the port sfp, but by the usual Ethernet, since the sfp will be busy by GiPon
P.S I know that probably my conceived configuration may show nonsense, but it is going to take 5-7 years and with an eye on the fact that in Moscow there will be a 10 gigabit Gipon that I will use.
